It is narrated from Hazrat Umm Hani (may Allah be pleased with her) that I asked the Prophet (peace and blessings be upon him) about the meaning of the Divine command «وَتَأْتُونَ فِي نَادِيكُمُ الْمُنْكَرَ» . The Prophet (peace and blessings be upon him) said: "It was the practice of the people of Lot that they would throw pebbles at passersby on the road and mock them; this is the detestable act that they used to do."
